ccf-0.18.0

Changed

• endpoint_metrics is renamed api/metrics and now returns an array of objects instead of nested path/method objects (#2068).
• Governance proposal ids are now digests of the proposal and store state observed during their creation, hex-encoded as strings. This makes votes entirely specific to an instance of a proposal without having to include a nonce. (#2104, #2135).
• quote endpoint has been renamed to quotes/self (#2149).
• TxViews have been renamed to MapHandles, to clearly distinguish them from consensus views. Calls to tx.get_view must be replaced with tx.rw.
• tx.rw does not support retrieving multiple views in a single call. Instead of auto [view1, view2] = tx.get_view(map1, map2);, you must write auto handle1 = tx.rw(map1); auto handle2 = tx.rw(map2);.

Added

• Added get_version_of_previous_write(const K& k) to MapHandle. If this entry was written to by a previous transaction, this returns the version at which that transaction was applied. See docs for more details.

Removed

• The x-ccf-global-commit header is no longer sent with responses (#1586, #2144). This was a hint of global commit progress, but was known to be imprecise and unrelated to the executed transaction. Instead, clients should call /commit to monitor commit progress or /tx for a specific transaction.
